The problem first started about 100km after my mom put about 20ltrs of fuel in. She fueled up while out in the bush at a remote location in western Alberta. So I was thinking fuel problems or water in the gas being the gas station was not a regular style but more of what you would see on a farm!
The problem is intermittent but is doing it 95% of the time. It seems to be not as bad while idling or cruising with very little pressure on the gas peddle. Its that 5% of the time it seems to run fine. Then 2 seconds later it spudders/misfires/hesitates. Especially if I give it more gas while under load. The more load I put the worse it gets. It seems to be a fuel problem or detination but.
I have checked for codes and received only code 12. I have drained the fuel tank and refilled with gas while adding a fuel treatment and changed the fuel filter. While doing this I also bled the fuel lines up to the fuel rail by disconnecting the fuel line at the rail and turning the key forward to push fuel through the line. I also did this while having the fuel filter off.I did this several times and pushed through aprox. 2 liters of fuel! I have checked for vacuum leaks and found none, and checked the plug wires. I pulled the spark plugs and they were very black/sooty as if its running rich, so I cleaned them(they are fairly new) and reinstalled. I do not smell/see any fuel in the oil. Also I am not leaking any oil/coolant anywhere. The exhaust fumes however do smell somewhat like gas! I have also cleaned the wiring harness that hooks up to the ignition coil and cleaned the ignition coil with electrical contact cleaner.
I am stuck on what to do next or even were to look for the problem. As stated it started just after fueling up out in the bush so I immediately thought fuel. And it feels like fuel/detination problems.
Thanks for anytime and replies!
